  • Aluminum nitride body having graded metallurgy
    Patent number: 5682589
    Abstract: Disclosed is an aluminum nitride body having graded metallurgy and a method for making such a body. The aluminum nitride body has at least one via and includes a first layer in direct contact with the aluminum nitride body and a second layer in direct contact with, and that completely encapsulates, the first layer. The first layer includes 30 to 60 volume percent aluminum nitride and 40 to 70 volume percent tungsten and/or molybdenum while the second layer includes 90 to 100 volume percent of tungsten and/or molybdenum and 0 to 10 volume percent of aluminum nitride.

  • Multilayer ceramic substrates having internal capacitor, and process for producing same
    Patent number: 5655209
    Abstract: Process for producing multilayer ceramic substrates using greensheet technology and thin dielectric ceramic greensheets for miniaturization purposes. The process avoids the screening of the thin greensheets by forming self-supporting fusible particulate metal electrode layers, interposing them with the thin greensheets and sintering the assembly to form the multilayer substrates such as integrated capacitors.
